Application filed August a, 1912. Serial no. iiaiar.

To all whom it may concern:

Be it known that I, THADDEUS B. BIKER, a citizen of the United States,and a resident of Allenhurst, in the county of Monmouth and State of NewJersey, have invented certain new and useful llmprovements inCarbureters, of which the followin is a specification.

The invention relates to improvements in carbureters for hydrocarbonengines, and it consists in the novel features, arrangements andcombinations of parts hereinafter described, and particularly pointedout in the claims. a

The object of my invention is to provide a simple and highly eflicientcarbureter for automatically supplying gas of the requisite quantity andquality to the cylinder of an engine, in accordance with the work to beperformed.

1 contemplate the use of my carbureter in connection with the cylindersof automobile engines for supplying gas theretof The carbureter of myinvention comprises preferably a cylindrical casing aflording acarbureting chamber for the air and gas to be connected by suitablepiping with the engine cylinder, and a receptacle for the gasolene, saidreceptacle surrounding the carbureting chamber and to be connected witha suitable tank or source of supply for the gasolene. The receptaclecontaining the gasolene will be provided with a float for closing, whenthedesired quantity of gasolens has entered said receptacle, a valvecontrolling the inflow of gasolene from the tank or other source ofsupply to the rece'ptacle, and said receptacle will beconnect- 4 ed by asuitable conduit and valve mechanism with the carbureting chamber of thecarbureter, said valve mechanism being adapted to permit of a variabledischarge of the gaso-lene in accordance with the requirements andpreferably being located about the pivotal axis of and discharging belowa suitable valve of the butterfly type employed for controlling thepassage of air from the lower to the upper portion of said chamber. Thecarbureting chamber is provided at its lower portion with a suitable airinlet and an automatic check-valve therefor. The butterfly valvecontrolling the passage through the carbureting chamber and the valve orcontrol mechanism for se curing the variable discharge of the gasolene,are preferably connected together and j operate synchronously to admitproper proportions of air and gasolene in accordance with the workrequired, whereby as the butterfly or air valve is turned to increasethe opening through the carbureting chamber,

the said control mechanism will likewise open to a greater extent tosupply the requislte quantity of gasolene to the increased quantlty ofair then passing through the carbureter.

My invention results in the attainment of proper combustion, highefliciency in the englue and great economy in the consumption of thegasolene, as well as accomplishing other important advantages.

The invention and the preferred means for carrying the same intoefilect, will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which Figure 1 is a side elevation of a carbureter constructed inaccordance with and embodying my invention; F i 2 is a top view of thesame, the pipe lea ing to the engine being in section on the dotted line2-2 of Fig. 1; Fig. 3 is an elevation of the same, taken from the righthand sides of Figs. 1 and 2; Fig. 4 is a vertical section through thecarbureter, taken on the dotted line 4% of Fig. 2; Fig. 5 is ahorizontal section, on a smaller scale, taken on the dotted line 55 ofFig. 4; Fig. 6 is a detached vertical section through the upper portionof the carbureting chamber and butterfly valve therein, taken on thedotteolline 6-6 of Fig. 4e, and Fig. 7 is a detached side elevation ofone member of the valve-mechanism controlling the discharge of gasoleneto the carbureting chamber.

In the drawings 10 designates the exterior cylindrical shell or casingof the carbureter, 11 a top plate thereon, 12 a bottom cap appliedthereto, 13 a vertical tubular section erates through the pivoted plate16, as the gasolene lowers in the receptacle 15, to open the valve 23 sothat an additional supply of the gasolene may flow into the receptacle15.

\Vhe'n the float 14 is elevated by an admis-' sion of a proper quantityof gasolene to the receptacle 15, it acts to turn the outer end of theplate 16 downwardly within thereceptacle 21 and permits or effects theseating of the valve 23 and the cutting 011' of any further supply ofgasolene through the inlet 22.

The outlet for gasolene from the receptacle 15 to the carburetingchamber in the tubular section 13 is through the tubular valve-member 24and tubular valve-member 25, to the latter of which a butterfly valve 26is connected by means of a strap or plate 2'7 said valve 26 normallyextendln' transversely across the carbureting cham er and being seatedon a square or polygonal ortion 28 of said tubular member 25. he strapor plate 27 engages the lower side of the square portion 28 of thetubular member 25, as more clearly shown in Fig. 6, and is riveted tosaid valve 26. The tubular valve member 25 is adapted to have a rotarymotion and in doing so to tilt the valve 26 in controlling the passageof air and gasolene through the carbureting chamber to the upper side ofsaid valve. The valve 26 and strap 27 are not rigidly fastened to thetubular member 25, but are mounted thereon and the valve 26 movestherewith during the rotary motion of said member 25, but in theconstruction presented the member 25 also has imparted to it a limitedlongitudinal movement,'and during this movement the square portion 28 ofsaid member has a sliding action between the valve 26 and strap or plate27. The tubular valve member 24 is rigid with the casing 13, beingsecured to it by means of a screw 29, and said member 24 is open at bothends, its outer end being in communication with a conduit or verticalopening 30 extending upwardly from within the receptacle 15 to saidmember 24, as shown in Fig. 4. The tubular valve member 24 extendstransversely of the carbureting chamber and to about the vertical centerthereof, where it is engaged with the inner tubular end 31 of the member25 with which it coacts, said end 31 being formed in its lower side witha slot 32 (Fig. 7) which constitutes the final outlet for the gasoleneto the carbureting chamber. I re-ferably annularly reduce the inner endof the tubular member 24 to receive the end 31 of the member 25, asshown in Fig. 4, thus leaving a substantially uniform surface to receivethe butterfly valve 26. The tubular member 24 is circular incross-section, and hence when the valve member 25 is turned and carriesthe valve 26 with it, said valve may readily turn on the surface of themember" 24. The tubular valve member 25 has a threaded intermediatesection 33 held within an internally threaded section 34 constituting aportion of the main casing 10, and said member 25 has at its outer end anon-threaded portion 35 upon which is secured a crank 36 to which anoperatin rod'37 is connected and which is preferaby formed with two arms38, 39 standing at right angles to each other and each carrying anadjusting or stop-screw 40 adapted on the movement of said crank 36 toengage a stationary stop 41 on the casing 10 and thereby limit theaction of the crank 36. The throw of the crank-arm 36 may be regulatedat will by the proper adjustment of the stop-screws 40.

The arm 36 is fastened, as by a screw 42, to the valve-member 25, andhence when said arm is actuated from the operating rod 37, it will turnthe valve-member 25 in one direction or the other in accordance with thedirection of movement of said arm,and this turning or rotary movement ofthe tubular valve-member 25 effects, through the engaging threads on thesame and the section 34 of the main casing, a longitudinal travel ofsaid member toward or from the valvemember 24 and the consequentenlargement or reduction of the opening through the slot 32 at the innerend of the valve-member 25. When the valve-member 25 travels outwardlyin a direction from the valve-member 24 the internal space between thefacing inner ends of said valve members is enlarged, and a more extendedportion of the slot 32 becomes exposed in view of the travel of the end31 with the valve member 25 in a direction outwardly from thevalve-member 24. When the valve-member 25 is turned to travel inwardlytoward the valve-member 24, as when a less quantity of gasolene isrequired, the end 31 of said member 25 travels upon the end'of thevalve-member 24 and the latter closes ofl a portion of the slot'32. Icontemplate that at all times a portion of the slot 32 shall be open forthe escape of gasolene. The longitudinal movement of the valve-member 25serves to aid in controlling the feed of gasolene into the carburetingchamber, but in order to obtain absolute satisfaction in feeding thegasolene and certainty in the operation of the carsaid valve member 25and has its pointed end arranged to enter the inner end of the openingthrough the valve member 24 and to more or less close said opening underthe varying requirements of the engine employing the carbureter. Theneedle-valve 43 is provided with a threaded section 44 engaging aninternal thread formed Within the member 25, and said needle-valve isprovided at its outer end with an operating head or wheel 45 by whichthe valve may be given an independent longitudinal movement within thetubular member 25 in first adjusting the carbureter to the engine, andthereafter be given rotary movements synchronously with the rotarymovements of the tubular member 25, and also a longitudinal travelingmovement with the said valve member 25. The needle-valve 43 is given aprimary adjustment according to the needs of the engine, and thereafterit is at all times stationary in its relation with the valvemember 25and turns and moves longitudinally therewith. When the valve-member 25moves outwardly in a direction from the valve-member 24 the needle-valvemoving with said valve member 25 enlarges the discharge opening from theinner end of the valve-member 24, and when said valvemember 25 movesinwardly toward said valve-member 24 the needle-valve 43 by entering thedischarge opening from said member 24 partly closes the same, and inthat way restricts the escape of gasolene therefrom. In order that theremay be no tendency whatever for the valve-member 25 to turn on theneedle valve 43, T provide the wheel or head 45 with a serrated edge andengage this edge with an arm 46 extending from the crank 36 so that withevery movement of said crank tending to turn the valve member 25 thewheel 45 and needle-valve 43 will receive a corresponding movement.

The butterfly-valve 26 is operated from the tubular valve-member 25, andhence with every turning motion of said valvemember the butterfly valvewill be more or less opened or closed. When the valvemember 25 is movedto increase the dis charge of gasolene, this action will open thebutterfly valve 26 proportionately, and when the valve-member 25 isturned to close ofl a part of the discharge of gasolene it will, at thesame time, proportionately close th valve 26, and hence by the primaryadjustment of the needle-valve 43 and the regulatable discharge of gasand air into the carbureting chamber, I am enabled to supply the enginewith gas of the requisite quantity and quality in accordance with thework to be performed.

The upper or cap plate 11 has a central bore constituting a continuationof the carbureting chamber. The bottom cap 12 contains an inlet anddrain chamber 47 formed with a laterally disposed tubular member 48which forms the inlet for air to the lower end of the carbureter. Thechamber 47 is below a check-valve 49 which is normally held on its seatby a coiledspring 50. During the use of the carburcter the valve 49 willbe automatically opened toa greater or less extent. as may be required,by the suction created by the piston of the engine on its suctionstrokes. The spring 50 is held against the valve 49 by an adjustablestem 51 and nut 52.

The top and bottom plates 11, 12 may be removably clamped against theends of the casing 10 by means of suitable rods or by other convenientmeans.

The operation of the carburetor will he understood from the foregoingdescri tion without further extended detailed exp anation.

The carbureter having been applied to position, and the receptacle 15having been supplied with gasolene, the operation of the air orbutterfly-valve 26 and the gasolene discharge valve mechanism below saidbutterfly-valve will be under the control of greater or less extent, asthe requirements of the engine may demand. It is one of the importantfeatures of the invention that the driver may regulate the quantity ofgasolene that shall escape to the carbureting chamber and that at thesame time-he may control by the position of the valve 26 the" quantityof air in said chamber to mix with the gasolene. T designedly locate thedisroe" charge orifice for gasolene to the carbure'ting chamber belowthe valve 26, which location for said discharge orifice ll find in theconstruction presented herein, to be of advantage in securing the propermixture of the gasolene and air and efliciency in the engine. The valve26 will normally be left slightly tilted so as to permit a certainquantity of air to be drawn upwardly above the same, and in the use ofthe carbureter the said valve will of course be more or less opened asrequirements may demand, and the opening for the discharge of thegasolene will be controlled accordingly. The initial adjustment of thecarburetor to the engine will be accomplished through the needle-valve43, and thereafter, as hereinbefore explained, the needle-valve 43 andvalve-member 25 will both rotate and travel together when actuated bythe driver through the rod 37 and intermediate connections.

I do not limit my invention to all of the details of form andconstruction hereinbefore described, since obviously the same may bemodified in many respects without departing from the spirit of theinvention.
